The DG447DV-T1-E3 is a single-pole single-throw high voltage Analogue Switch designed to provide high speed, low error switching of precision analogue signals. This has one normally closed switch, while the other switch is normally open. This analogue switch is designed to provide high speed, low error switching of precision analogue signals. The primary application areas are in the routing and switching in telecommunications and test equipment. Combining low power, low leakages, low on-resistance and small physical size, the DG477 is also ideally suited for portable and battery powered industrial and military equipment.
